Hereinafter, embodiments of the present invention will be described. As shown in FIG. 1, the PET bottle container auxiliary tool 1 according to the embodiment of the present invention has a structure including an adapter portion 2 and a loading portion 3. When the PET bottle storage auxiliary tool 1 is attached to the PET bottle 5, it becomes a storage device 6. In the storage device 6, the used insulin injection needle or the like is charged into the charging unit 3 in a state where the PET bottle 5 is upright or substantially upright. The size of the insulin injection needle varies depending on the length of the needle body, but is generally smaller than 20 mm on all sides including the attachment portion. The storage device 6 is suitable for an insulin injection needle, but it can also be used for other devices.

The adapter portion 2 has a coupling mechanism 21 as shown in FIGS. 2 (a) and 2 (b). The coupling mechanism 21 is a mechanism that can be coupled to the mouth cylinder portion 51 of the PET bottle 5. Further, the adapter portion 2 has a cylindrical shape and has a hollow portion 22. As shown in FIG. 3, the hollow portion 22 communicates with the inner space portion 52 of the PET bottle 5 when it is connected to the mouth cylinder portion 51 of the PET bottle 5. Further, the hollow portion 22 (and the through hole 31 described later in the charging portion 3) has an inner diameter (for example, 20 mm or more) through which an insulin injection needle or the like can pass.

The coupling mechanism 21 has a configuration in which a passing hole 21a and a metal wire 21b are provided. The passage hole 21a leads to the outside from the hollow portion 22 of the adapter portion 2. The passage hole 21a is formed in a part of the side wall 23 of the hollow portion 22. As shown in the figure, the passage hole 21a has a groove-shaped portion 21aa in the circumferential direction and a width shorter than that so that the handle portion 21bb of the metal wire 21b described below can be passed through and exposed to the outside. It is possible to have a notch portion 21ab formed up to the end of the side wall 23.

The metal wire 21b has a ring portion 21ba wound one or more turns along the inner wall surface of the side wall 23 of the hollow portion 22, and a handle portion 21bb whose vicinity of both ends is exposed to the outside through the passage hole 21a. The metal wire 21b has a restoring force.

In the coupling mechanism 21, the inner diameter of the ring portion 21ba of the metal wire 21b is increased by the operation of bringing the vicinity of both ends of the handle portion 21bb closer to each other. When the mouth cylinder portion 51 of the PET bottle 5 is inserted into the hollow portion 22 and the above operation of the handle portion 21bb is stopped with the inner diameter of the ring portion 21ba expanded, as shown in FIG. 3, the ring portion 21ba is caused by the restoring force. The inner diameter of the pipe is narrowed to hold the mouth cylinder portion 51. Therefore, the user can easily attach the PET bottle storage auxiliary tool 1 to the PET bottle 5. Further, the user can easily remove the PET bottle storage auxiliary tool 1 from the PET bottle 5 by operating the metal wire 21 and pulling out the PET bottle 5 in the same manner as the attachment.

Further, as shown in FIG. 4, it is also possible to insert and hold the cap 7 screwed into the mouth cylinder portion 51 of the PET bottle 5 in the vicinity of both ends of the handle portion 21bb of the metal wire 21b. By doing so, when the PET bottle storage auxiliary tool 1 is removed from the PET bottle 5, the caps 7 held near both ends of the handle portion 21bb are screwed into the mouth tube portion 51 of the PET bottle 5 to seal. Can be done. Then, the PET bottle 5 can be sealed even if the PET bottle to be newly used is not present on the spot.

A coupling mechanism that can be used instead of the coupling mechanism 21 will be described below.

The coupling mechanism 21A shown in FIGS. 5 and 6 has a configuration in which a pair of passing holes 21Aa and 21Aa and a metal wire 21Ab are provided. The pair of passing holes 21Aa and 21Aa communicate with the outside from the hollow portion 22 of the adapter portion 2. The pair of passage holes 21Aa and 21Aa are formed in a part of the side wall 23 of the hollow portion 22.

The metal wire 21Ab has a pair of linear sandwiching portions 21Aba and 21Aba, and a connecting portion 21Abb connecting the sandwiching portions 21Aba and 21Aba. The pair of sandwiching portions 21Aba and 21Aba pass through the pair of passage holes 21Aa and 21Aa, and a part thereof (indicated by reference numeral A in FIG. 5B) is inward from the side wall 23 (in the hollow portion 22). ) Is sticking out. The metal wire 21Ab has a restoring force.

In the coupling mechanism 21A, when the mouth tube portion 51 of the PET bottle 5 is inserted into the hollow portion 22, the pair of sandwiching portions 21Aba and 21Aba of the metal wire 21Ab expands, and as shown in FIG. 6, the mouth tube portion is due to the restoring force. 51 is sandwiched and held. Therefore, the user can easily attach the PET bottle storage auxiliary tool 1 to the PET bottle 5. In addition, the user can easily remove the PET bottle storage aid 1 from the PET bottle 5 by pulling out the PET bottle 5. It is also possible to hold the cap 7 screwed into the mouth cylinder portion 51 of the PET bottle 5 on the tip side (opposite side of the connecting portion 21Abb) of the pair of sandwiching portions 21Aba and 21Aba.

The coupling mechanism 21B shown in FIGS. 7 and 8 has a configuration in which a pair of passing holes 21Ba and 21Ba and a ring-shaped elastic body 21Bb are provided. The pair of passage holes 21Ba and 21Ba communicate with the outside from the hollow portion 22 of the adapter portion 2. The passage holes 21Ba and 21Ba are formed in a part of the side wall 23 of the hollow portion 22.

The ring-shaped elastic body 21Bb passes through the pair of passage holes 21Ba and 21Ba described above, and a part thereof (indicated by reference numeral A in FIG. 7B) is inward from the side wall 23 (in the hollow portion 22). It is sticking out.

In the coupling mechanism 21B, when the mouth tube portion 51 of the PET bottle 5 is inserted into the hollow portion 22, the ring-shaped elastic body 21Bb expands, and as shown in FIG. 8, the mouth tube portion 51 is sandwiched and held by the restoring force. do. Therefore, the user can easily attach the PET bottle storage auxiliary tool 1 to the PET bottle 5. In addition, the user can easily remove the PET bottle storage aid 1 from the PET bottle 5 by pulling out the PET bottle 5.

The coupling mechanism 21C shown in FIG. 9 is a female screw portion screwed into the mouth cylinder portion 51 of the PET bottle 5. The adapter portion 2 is coupled to the mouth cylinder portion 51 of the PET bottle 5 by screwing the coupling mechanism 21C. Therefore, the PET bottle storage auxiliary tool 1 having the coupling mechanism 21C is slightly less easy to attach and detach than the one having the coupling mechanism 21, the coupling mechanism 21A or the coupling mechanism 21B described above, but has a more structural structure. It's simple.

The coupling mechanism 21D shown in FIG. 10 and the coupling mechanism 21E shown in FIG. 11 are elastically deformed portions of the adapter portion 2 that elastically deform when the mouth cylinder portion 51 of the PET bottle 5 is inserted. The coupling mechanism 21D and the coupling mechanism 21E are elastically deformed to be brought into close contact with the mouthpiece 51. Therefore, the PET bottle storage aid 1 having the coupling mechanism 21D or the coupling mechanism 21E has the mouth cylinder portion of the PET bottle 5 as compared with the one having the coupling mechanism 21, the coupling mechanism 21A, the coupling mechanism 21B, and the coupling mechanism 21C described above. The strength of the bond to 51 tends to be low, but the structure is simpler.

Specifically, in the coupling mechanism 21D, the thickness of the side wall 23 of the hollow portion 22 of the adapter portion 2 is reduced in the vicinity of the end portion on the side where the mouth cylinder portion 51 of the PET bottle 5 is inserted. Further, the side wall 23 of the hollow portion 22 has a narrow end on the side where the mouth cylinder portion 51 of the PET bottle 5 is inserted, and the inner diameter is small. As a result, when the mouth tube portion 51 of the PET bottle 5 is inserted, it is elastically deformed, and by elastically deforming, it is brought into close contact with the mouth tube portion 51. Further, the coupling mechanism 21E is made of a material in which the side wall 23 of the hollow portion 22 of the adapter portion 2 is elastically deformable. As a result, when the mouth tube portion 51 of the PET bottle 5 is inserted, it is elastically deformed, and by elastically deforming, it is brought into close contact with the mouth tube portion 51. The coupling mechanism 21E may be an elastically deformable separate member bonded to the inside of the side wall 23 of the hollow portion 22 of the adapter portion 2 and used as the coupling mechanism 21E.

As shown in FIG. 12, the charging portion 3 is provided with a through hole 31 communicating with the hollow portion 22 of the adapter portion 2 at the bottom portion 3a. Further, the input portion 3 and the adapter portion 2 may be bonded by adhesion, but may also be coupled by forming a male screw 32 on the bottom portion 3a and screwing the female screw 24 (see FIG. 3) formed on the adapter portion 2. can. When they are connected by screwing, if either the adapter portion 2 or the loading portion 3 is broken, the replacement work is easy.

The inner diameter D of the end portion 3b of the insertion portion 3 is set from the inner diameter of the through hole 31 so that the insulin injection needle can be easily inserted and the injected insulin injection needle smoothly enters the through hole 31 and falls. Is also getting bigger. As shown in FIGS. 12 and 13, the end portion 3b of the charging portion 3 preferably has a rounded shape. This is in consideration of not damaging the user's hand in the event of accidental contact.

Further, as shown in FIG. 14, the charging portion 3 can be provided with a cap holding portion 33 capable of holding a cap 7 that can be screwed into the mouth cylinder portion 51 of the PET bottle 5. More specifically, the cap holding portion 33 may have a structure in which a male screw portion 33a into which the cap 7 can be screwed is formed at the tip portion of the cap holding portion 33 protruding from a part of the outer surface of the charging portion 3. By doing so, when the PET bottle storage auxiliary tool 1 is removed from the PET bottle 5, the cap 7 held by the cap holding portion 33 is screwed into the mouth cylinder portion 51 of the PET bottle 5 to seal the PET bottle 5. Can be done. Then, the PET bottle 5 can be sealed even if the PET bottle to be newly used is not present on the spot. Further, the cap 7 can be firmly held by screwing it into the male screw portion 33a of the cap holding portion 33.

Further, as shown in FIGS. 15 and 16, the PET bottle storage auxiliary tool 1 preferably includes a filter unit 4. The filter portion 4 has a portion (filter main body portion) 41 extending toward the inner space portion 52 of the PET bottle 5 along the inner wall surface of the side wall 23 of the hollow portion 22 of the adapter portion 2. The filter portion 4 usually has a mounting portion 42, and is fixed to the charging portion 3 or the adapter portion 2 by adhesion or the like. The filter main body 41 has an inner diameter (for example, 20 mm) through which an aggregate of long plates (for example, an aggregate of four long plates as shown in FIGS. 15 and 16) can pass an insulin injection needle. The above) makes it tubular. It is preferable that the filter main body 41 extends to the inside of the inner space 52 of the PET bottle 5 to some extent. With such a structure of the filter unit 4, even if the PET bottle 5 falls down from the upright state, it is possible to prevent the insulin injection needle stored in the PET bottle 5 from popping out from the charging unit 3.

It is preferable that the tip of each of the long plates constituting the filter main body 41 is bent toward the center and the lengths are different from each other. Then, as shown in FIG. 17, the insulin injection needle passes through the tip of the filter main body 41 while changing its trajectory, and then falls into the PET bottle 5. Further, even if the PET bottle 5 falls down from the upright state, it is extremely difficult for the insulin injection needle to enter the filter main body 41 from the opposite direction because it must enter while changing the trajectory. In addition, in FIG. 17, the insulin injection needle is indicated by reference numeral N, and shows that the trajectory changes by drawing two states in one cross section. Similarly, even in a cross section perpendicular to this one cross section, the insulin injection needle N falls while changing its trajectory.

As described above, the PET bottle storage aid 1 is suitable for inserting a used insulin injection needle into the PET bottle 5, and is very easy for the user to handle. In addition, since the PET bottle storage auxiliary tool 1 has a simple structure, it does not cost much.

Although the PET bottle container assisting tool according to the embodiment of the present invention has been described above, the present invention is not limited to the one described in the above-described embodiment, but is within the scope of the claims. Various design changes are possible.
